Looks like I'm in luck with the ECU, there is only one thing I'm not sure about!

The markings on the ECU read

A56 R12 JA Nissan A56-R12 L18 1Z07 UNISIA JECS CORPORATION JAPAN

Which should be fine assuming the L18 1Z07 is the serial number, i.e. Iain's is L18 1Y03.

The part I'm not sure about is that Iain's is stamped with a little circle and a D7, the one coming back from Japan with my name on it has D8. Could this be a firmware thing? Can anyone get any gossip, maybe it's just the quality control person's number or something?

I've included some piccies, I want to start getting excited that it's right but I'm not 100% sure!

i bet you its firmware, plug it in and see if it works dude. if its 100% from a VQ25DET equipped M35, i rekon its gonna work.....

did they mention what year it was from? mines an 01 and im game enough to try it in my car

It's a December 2001, I would like to know it works before I start making arrangements for the remap with SAS.

I may even try it in mine, is it easy to remove the glovebox to get to the ECU?

I've asked Ken if he can get any indication of what the D# is before he departs Japan.

its pretty easy dude, youll work it out, i think its about 6 screws. no need to remove your ecu, just unplug it and plug in the other one and leave it hanging

Just let it dangle eh? Won't do any damage if I floor it with the new ECU swinging on the wire? :blush:

I'm still waiting to confirm with SAS but at this point in time I have paid for the ECU, they were going to reimburse me BUT I've asked if they need the ECU past the initial trial and development stage i.e. my tune. If they don't, like Andy has with the turbo, I will hold the ECU in my possession incase anyone needs one urgently to replace there's, the original cost plus a little extra will be required but I can tell you all that these ECU's are not easy to find!!!!! Even Iain will confirm that we have only sighted one on Yahoo Japan Auction (IM) since we have been looking and I've tried all around australian wrecker's with M35's and those that did have a VQ25DET and ECU would not seperate them.

Anyway, I'll post a message announcing that I will have an ECU on hand incase one of you EManage Ultimate guys fry your ecu :)

I'm hoping to have the ECU in a week or two so I can start arranging everything with SAS.

I'll give the ECU a test run before I take it in just incase anything isn't quiet right.

Is there any way (like via the display screen) to check the revision date etc. of the firmware on the ecu?

I'll looking forward to this remap, should be awesome! Hopefully I can squeeze a bit more out of it than you EManage Ultimate boys :)

im sure youll be able to! no piggy back is as good as a remap/fully programmable ecu.

lets just hope they CAN remap them :)

You'd think because Nissan mapped them to begin with they *should* be remappable :D

I sent SAS the link to your pics the other day, so he can have a squiz at the internals pic.

I'll see how things go when the spare ECU arrives from Brisbane, the ECU's *must* be remappable especially when you have products like the Nismo ECU on the scene, that's probably just a remapped stock M35 ECU.

ok im taking a leap of faith for that nismo ECU. so assuming i win it, ill be selling the emanage if anyones interested. might chuck it in the FS section soon.........

Good Luck! (sincere, not sarcastic :) )

Better get some octane booster unless you want to ping your life away...

detonation can be caused by air that is too hot also as well as lack of fuel. a FMIC will allow me to run more boost which this ECU is already programmed to do!

The boost level is set by the brass insert in the wasegate line, unless you have a boost controller it wont change.

The Nismo ecu would be great as it will speed up gear changes and improve most aspects of the engine but it is tuned to 101 octane. If you cant remap it due to language problems you might need to fit the Emanage to adjust things down, I wouldnt sell it just yet...

ill see how i go for the moment.

boost is ECU controlled mate, there is a solanoid that controls the bypass to the actuator. sometimes its good to retain the factory boost control as it can drop off boost levels in the event of detonation. that brass restrictor slows down how quickly the boost comes on, yes it does affect boost a little. on SR20s if you removed it, you got a psi or 2 more and boost came on a lot faster (compared to factory)

      R33 Fuel Pump & Brakes after alarm swap

      By Jarsky · Posted

      Thought I would get some advice from others on this situation.    Relevant info: R33 GTS25t Link G4x ECU Walbro 255LPH w/ OEM FP Relay (No relay mod) Scenario: I accidentally messed up my old AVS S5 (rev.1) at the start of the year and the cars been immobilised. Also the siren BBU has completely failed; so I decided to upgrade it.  I got a newer AVS S5 (rev.2?) installed on Friday. The guy removed the old one and its immobilisers. Tried to start it; the car cranks but doesnt start.  The new one was installed and all the alarm functions seem to be working as they should; still wouldn't start Went to bed; got up on Friday morning and decided to have a look into the no start problem. Found the car completely dead.  Charged the battery; plugged it back in and found the brake lights were stuck on.  Unplugging the brake pedal switch the lights turn off. Plug it back in and theyre stuck on again. I tested the switch (continuity test and resistance); all looks good (0-1kohm).  On talking to AVS; found its because of the rubber stopper on the brake pedal; sure enough the middle of it is missing so have ordered a new one. One of those wear items; which was confusing what was going on However when I try unplugging the STOP Light fuses (under the dash and under the hood) the brake light still stays on. Should those fuses not cut the brake light circuit?  I then checked the ECU; FP Speed Error.  Testing the pump again; I can hear the relay clicking every time I switch it to ON. I unplugged the pump and put the multimeter across the plug. No continuity; im seeing 0.6V (ECU signal?) and when it switches the relay I think its like 20mA or 200mA). Not seeing 12.4V / 7-9A. As far as I know; the Fuel Pump was wired through one of the immobiliser relays on the old alarm.  He pulled some thick gauged harness out with the old alarm wiring; which looks to me like it was to bridge connections into the immobilisers? Before it got immobilised it was running just fine.  Im at a loss to why the FP is getting no voltage; I thought maybe the FP was faulty (even though I havent even done 50km on the new pump) but no voltage at the harness plug.  Questions: Could it be he didnt reconnect the fuel pump when testing it after the old alarm removal (before installing the new alarm)?  Is this a case of bridging to the brake lights instead of the fuel pump circuit? It's a bit beyond me as I dont do a lot with electrical; so have tried my best to diagnose what I think seems to make sense.  Seeking advice if theres for sure an issue with the alarm install to get him back here; or if I do infact, need an auto electrician to diagnose it.

      After market rear camber arm adjustment

      By Duncan · Posted

      Then, shorten them by 1cm, drop the car back down and have a visual look (or even better, use a spirit level across the wheel to see if you have less camber than before. You still want something like 1.5 for road use. Alternatively, if you have adjustable rear ride height (I assume you do if you have extreme camber wear), raise the suspension back to standard height until you can get it all aligned properly. Finally, keep in mind that wear on the inside of the tyre can be for incorrect toe, not just camber

      After market rear camber arm adjustment

      By V35Newbie · Posted

      I know I have to get a wheel alignment but until then I just need to bring the rear tyres in a bit they're wearing to the belt on the inside and brand new on the outside edge. I did shorten the arms a bit but got it wrong now after a few klms the Slip and VDC lights come on. I'd just like to get it to a point where I can drive for another week or two before getting an alignment. I've had to pay a lot of other stuff recently so doing it myself is my only option

      By Duncan · Posted

      You just need a wheel alignment after, so just set them to the same as current and drive to the shop. As there are 2 upper links it may also be worth adding adjustable upper front links at the same time; these reduce bump steer when you move the camber (note that setting those correctly takes a lot longer as you have to recheck the camber at each length of the toe arm, through a range of movement, so you could just ignore that unless the handling becomes unpredictable)

      After market rear camber arm adjustment

      By V35Newbie · Posted

      I got adjustable after market rear camber arm to replace the stock one's because got sick of having to buy new rear tyres every few months. Can anyone please let me know what the best adjustment length would be. I don't have the old ones anymore to get measurements. I'm guessing the stock measurement minus a few mm would do it. Please any help on replacing them would be fantastic I've watched the YouTube clips but no-one talks about how long to set the camber arm to.
